Input Section
Because of the wide range of head unit output configurations all VVME
amplifiers have an adjustable input sensitivity of Gain The gain is not
a volume or a power limiting control like a throttle. It makes the amp more
sensitive to input from the stereo. with the gain up the amp will reach full output
at a lower volume setting on the deck. At higher gain settings the amp also
becomes more more sensitive to noise from the car s electrical system. Try to
run the gain at the lowest setting possible for you system.
“ ”
'
There is no correct gain setting Because
speakers require different power
demands to reach the same output the
gains most often need to be used to
compensate for these differences If you
tried to set all the gains at half way you
would probably find the system didn t
sound very good. Using good judgment
and listening carefully to each speaker is
still the best way to tune a system.

Crossover controls
A crossover is a device that removes unwanted frequencies from a speaker or
amplifier.A tweeter can easily be destroyed by bass notes if they are not
filtered out.Likewise a subwoofer will not sound natural if it is playing midrange
notes.A crossover removes these sounds from the speaker.As you might guess,
careful adjustment in need to ensure
that all the speakers are playing the
right sounds and that you are left with
no holes or low spots in the
frequency response.

Bass Boost
amplifiers have an adjustable bass boost.On the 4
channel DAB-4.1200N this is controlled by a VR selecting the most commonly
used BASS BOOST setting.Begin your adjustments at low volume.If you do not
hear any improvement then woofer does not need any BASS BOOST.
The Low Pass Filter(LPF) must be switched on for the bass boost to activate.
VVME MGB1.800/MGW1.800
Use Bass Boost carefully.The demands on
power output are tremendous.Try to
minimize the use by changing woofer
position or the enclosure size.

you have to go back and make some changes

Speaker outputs
This amplifier is a multi channel amplifier design. Meaning it has more than one
channel of speaker outputs. It is equipped with a large block style terminal for
speaker connection. Make this connection carefully and neatly. strip your wire
back and twist the exposed leads and insert them into the block terminal while
being
careful that there is no loose or frayed strands of
wire and tighten the Allen head screw down on the
terminal till the wire is tightly secured in place.If the
wires ever come in contact with each other the
amplifier will go into protection
.
Know your total ohm load before you make any
connections.
